LOOM.

SPECIFICATION forming part of Letters Patent No. 631 ,407, dated August 22, 1899.

Application filed May.2, 1898- Serial No. 679,534. (No model.)

To all whom, it nuty concern:

Be it known that I, HUGH ROBERT Ross, of Durham Street Mill, Belfast, in the county of Antrim, Ireland, have invented certain new and useful Improvements in-Loomsfor VVeaving, of which the following is a specification. My invention relates to weaving-looms, and is designed to change or replace the shuttle when the weft breaks or fails, instead of stop ping the loom, as hitherto, by an automatic motion actuated by the weft-fork operating a rotaryshuttle box or receiverl i It consists, essentially, in constructing the loom with a fixed or stationary cage or recep-I tacle placed at any convenient place at the side of the loom. to contain a number of full or threaded shuttles, a revolving shuttle-box on the end of theslay fitted with slides and cams to discharge the empty shuttles,'and levers or rods connecting the weft-fork with the actuating mechanism of th-erotati'ng box and shuttle cage or receptacle by means of which the box is rotated and a fresh shuttle supplied automatically on the breakage or failure of the weft. It will be fully described with reference to the accompanying drawings, in which sufficient of theordinary working parts of the loom are shown to illustrate the invention.

Figure l is a front elevation; Fig. 2, an end elevation; Fig. 3, a plan; Fig. 4, alongitudinal- At one endiof the loom I place a fixed stationary cage or receptacle'H to' hold or contain a number of shuttles G, placed one above the other or in other. suitable position, from which they can be delivered one at a time by. a reciprocating bar or ipusher h.

To'the endof the slay B, so as to oscillate to and fro with it, I affix or attach a circular revolving shuttle-box K, capable of carrying any desired number of shuttles: G and presenting them successively to the shuttle ac tuating mechanism as may be required.

In the drawings the revolving shuttle-box K is shown with four chambers to receive the shuttles, and these chambers are formed so that the shuttles can enter through the sides. Each chamber is provided with a spring or swell kwith outtnrned ear or lip k or of other suitable shape to permit of the shuttle compressing the spring as it enters the chamber from the cage or receptacle H. Each chamber In of the revolving shuttle-box K is also fitted with one or two slides L in the bottom, which operate to expel the shuttles from the chamber. The slides L are operated as the box rotates bya fixed or stationary cam M on the fixed spindle Z, on which the box rotates. The cams M push the slides forward when the chamber is inverted to discharge the shuttle. The slides and cams act direct upon the shuttle to force it out or may act upon the retaining spring or swell alone to withdraw it and allow the shuttle to fall out. A chute may be placed to receive the discharged shuttle and conveyit to a receptacle to receive it.

The shuttle-box is i-nclosed or cased with a circular cylindrical casing M, which acts as a guide or cover to retain the shuttle in position in the chamber 7c. It is provided with a slot or slit m in the top, the edges m extending over the chamberlc to hold the shuttle down when the loom is in operation.

The rotary shuttle-box K is supported at its outer end by a radial arm or rod N, which oscillates with the shaft 41, upon which the slay B is also pivoted. It is connected to the crank F by the connecting-rod f, by which it is operated to oscillate simultaneously with the slay B. Thus after each shot of the shuttle G the box K swings forward and approaches nearly close to the stationary shuttle cage or receptacle H, from which when the chamber 70 is emptyit receives afresh shuttle.

The-revolving shuttle-box K is caused to rotate as desired to bring each chamber 70 successively into position from which the shuttle can be put in action by the leverP,which is connected by a series of levers with suitable operating mechanism and with the weftfork D, whereby when the weft-thread is broken or absent the lever P is drawn down and the shuttle-box K rotated part of a revolution. The end of the shuttle-box K is provided with pegs p, with which the hook on the upper end of the lever P engages.

The revolving shuttle-box K is held in position by a spring-hammer R, pressed tightly against the square end of the cylinder by the spring 0', the tension of which is adjusted by the screws r.

The lever P for rotating the shuttle-box K is operated bya hooked lever P, attached to the opposite end of a pivoted lever O, to which both are pivoted. The lever 0 is raised bya cam s on the cam-shaft S at each revolution of the cam-shaft and raises the hooked lever P with it when the hook is pressed over or in a position to engage with the pin or peg o in the side of the lever 0. Thus the raising of the hooked lever P depresses the hooked lever P and causes the rotation of the shuttlebox K.

In normal position the hooked lever P is held by a spring p out of the path of the peg 0 in the lever 0, and it is pushed or forced into the position shown in Fig. 2 of the drawings by the crank T on the breakage or failure of the weft-thread.

The crank T is connected by the connecting-rod t with the pivoted lever T, the upper end of which engages with the slide or lever (I of the weft-fork D. The oscillating hammer-lever E is actuated in the usual way by the cam e and engages the catch on the end of the weft-fork when the weft breaks, by which the slide or lever (Z is drawn back, causinga movementof the pivoted leverT,which is transmitted through the crank T to the hooked lever P, which in turn is operated by the peg 0 of the lever 0.

The reciprocating bar or pusher 7b in the cage or receptacle II is operated by cranked levers V, by which the lower shuttle is pushed forward when required. The cranked levers V are operated in one direction by the lever V, which is connected thereto by a connecting spring or link 17 and in the opposite direction by the spring 1). The lever V is depressed by the cam or disk 5, carried by the disk 8 011 the cam-shaft S. The disks 8 s are moved into position to engage the lever V each time the hooked levers P I are operated to rotate the shuttle-box K. The pivoted lever O carries an arm IV with a pin or peg w in the end which engages with a link w and raises it when the lever is raised, bringing a bowl or runner to into contact with another cam s 011 the cam-shaft. The link to is also connected with another lever W, pivoted to a fixed bracket at its upper end, and the action of the cam s on the runner 10" moves it in a direction away from the cam. The lever WV is in contact with the disk 3 and when moved by the cam 6 slides the disk 8" along the cam-shaft S-until the disk 3 is over the lever V in position to depress it as the cam rotates. A spring 10 moves it back again. The levers are so arranged that the forward movement of the pusher h in the receptacle I-I commences when the crank F is nearly at the end of its outward stroke and the shuttle-box K almost in contact with the shuttle-receptacle H.

In operation the breakage of the weftthread permits the weft-fork D to engage the oscillating hammer-lever E, the motion of which is transmitted through the slide or bracket D d to the pivoted lever T and crank T to throw the hooked lever P into engagement with the oscillating lever 0. The movement of the oscillating lever o is then transmitted through the hooked lever P and pivoted lever O to the hooked lever P, and the shuttle-box is rotated. By the same operation the disk 8 is brought into contact with the lever V to operate the pusher h after the partial revolution of the shuttle-box K has taken place. The revolution of the shuttlebox K brings a full shuttle into position to be thrown across the web and so continue the weaving without stopping the loom and at the same time brings an empty shuttle into position to be discharged to be refilled or rethreaded and also brings an empty chamber h of the box II opposite the cage or receptacle H to receive a refilled or rethreaded shuttle.

IVhat I claim as my invention, and desire to protect by Letters Patent, is

1. In a loom for weaving, the combination with a stationary shuttle-receptacle fixed to the end frame, and a revolving shuttle-box, of mechanism for positively transferring a shuttle from the stationary receptacle to the revolving box and mechanism comprising internal stationary cams placed in the center of the revolving shuttle-box for positively discharging the spent shuttles from the revolving box while a fresh shuttle is simulta neously presented to the next stroke of the picker and an empty box presented before the receptacle to receive a full shuttle substantially as described.
